Sonet/SDH E4/Stm-1 Telecom Transformer 155Mbps 42uh SMD Pulse Isolation Module Transformer for High-Speed Network Interface

Sonet/SDH E4/Stm-1 Telecom Transformer 155Mbps 42uh SMD Pulse Isolation Module Transformer for High-Speed Network Interface. Fully optimized for SONET and SDH optical fiber transmission systems, ensuring stable high-speed clock and data link communication. Exceptionally low interwinding capacitance of only 6.0 pF max minimizes high-frequency noise coupling and boosts EMI immunity. Ultra-low leakage inductance of 0.10 uH max guarantees outstanding signal integrity and prevents narrow pulse distortion. Offers precise primary inductance options (36 uH for CL7301X, 42 uH for CL7302X) tailored for high-frequency signal shaping. Features a highly precise 1:1 turns ratio (plus or minus 5 percent) for perfectly balanced input and output signal matching. Built with 1500Vrms isolation voltage to protect downstream high-speed transceivers and logic circuits from line surges. Super compact 12.80x6.90x6.50 mm miniature SMT package saves valuable board space for high-density telecom line cards. 100% Lead-Free (Pb-Free) and fully RoHS compliant, making it easy for overseas buyers to clear green environmental audits. Ideal for optical transceivers, core routers, telecom multiplexers, and high-speed digital carrier systems. Produced under strict original factory conditions with reliable long-term supply capacity guaranteed by CoreLogic infrastructure.
